Hi mate. Maybe the same thing but I have a rally puma, my friend has a newer shape fiesta and another has a Mk6. All have suffered with a stuck rear brake shoe. They have always been when the weather was wet/damp and it got cold. Must freeze up somehow. once one of the cars couldnt actually be moved until the next day as it was so bad. Maybe the same problem

as above even the rear drums do it always the rear passenger side always in wet cold weather i find spraying the handbrake cable at all the points where it passes through with spray grease does solve it a lot of road gunk gets stuck up in there and causes it to stick but its something that you have to do every 3-6 months

Sound like the brake shoes/drums at the rear for me too. Had a similar problem with our Saxo a few years ago and they seized up completely. if that wasn't bad enough they seized up at the in-laws place so we had to stay longer while it got sorted.
